Re: Installing GCC-4.x in userspace / Compiling Octave from CVS

Thank you for your replies. I finally managed to jump through hoops,
GCC3.2 ->3.4 ->4.2.
Now I am building Octave using gfortran, and I got these undefined references.

I dont know how I can find a libg2c for gfortran or use g77 from gcc-3.4.
What am I supposed to be doing right now?
